e4, 1926. Serial no. means.

Referring now to the drawings in detail, there is shown in Figure 1 a portion of a door 10 and a door frame 11. Mounted upon the door 10 is a lock casing12 secured to the door as by means of screws 13. Secured'to the door frame 11 as by means of screws 14 is a part 15 having'a plate 16 which faces toward'the casing 12 upon the door. I

The lock mechanism contained within the casing 12 is shown herein as having two bolts 1? and 18. These bolts are removable into andout of the casing 12toward and away from the part 15 upon the door frame and are adapted when extended to project through an opening 19 in the plate 16, as shown inFigure 2. The bolts 17 and 18 shown herein are of a type which, after slid- 7 ing into operative position through the opening 19, are rotated to position their end projections 17a and 18a in back of the plate 16. The actuating mechanism for these bolts is not shown in. detail herein, since, in itself, it constitutes nopart'of thepresent invention. However, asshown in dotted lines in Figure 1', the bolts 17 and 18 are connected to a plate 20 which is mounted within the casing for sliding movement toward and away from the door frame. This plate 20 is moved by any suitable mechanism indicated at 21 in Figure 1, this'mechanisin being actuated by a suitable handle 22 from the inner side of the door and by akey from the outer side to move the plateQO so as to movethe bolts 17 andlS into their extended position'or retractedfposition. In Figure 1 the bolts are shown extended and entering the plate 16 on the door frame to lock the door in'closed po: sition, while in Figure i the bol s are shown retracted into the casing 12, the sliding plate 20 and the" operating mechanism 21 being correspondingly positioned as indicated by the dotted lines.

Preferably secured to the member 15 upon the door frame, by means of a swivel connection about a pin 231s a chain-24. The

' other end of the chain 24 is provided"with: I an end'n'iembercomprising an eye 25, a shank.

portion-26 and an enlargedend part comprising two 130111011827 and 28, the purpose of wh ch will be made clear hereinafter. Be

r cut away sufficiently to permit the part 27 to walls 31 beneath which the enlarged end 27 tween the eye 25 and the shank 26 the end member is preferably provided wlth a flange having a ltlblJGPCOVBlHlg 29 which prevents the chain from marring the door or door frame when it is hanging loosely as shown in Figure 1. This end of the chain is adapted to be received and held by a part of the casing 12 upon the door, as will be described presently, and the chain is of such length that when it is in operative position it permits opening of the door to a limited degree. Upon the member 15 is formed a housing 29 which forms a keeper for receiving the end of the chain, as shown in Figure 2, when the chain is not in use.

In the surface of the casing 12 upon the door is formed a recess or slot 30 which is adapted to receive and hold the end member of the chain. This slot 30 is somewhat elongated and is provided with overhanging overhanging edges 31.

7 As shown in Figure '3, the end member hollowed outand is provided with a projecting member 33 which is urged outwardly by a spring 3%. .Vhen the end member of the chain is insrted into the slot30 the member 33 comes against the base of the slot is depressed inwardly, against the action of the spring 3a, to permit lisertion of the end member to a sufiicient distance for the'part 27 to slide beneath the overhanging edges 31. At the end of the slot 30 adjacent to the door frame, at 35, the overhanging walls 31 are project therethrough but not suliicientlyto permit passage of the larger part 28. The spring 34;, acting through the member '33 which bears against the base of the recess, urges the end member outwardly so that the part 27 projects into the space 35, as shown in Figure 6. The parts 31 to the left of the part 35 will not permit passage of the part 27 therebetween and hence the end member of the chem cannot he slipped out of the 'J-i t tit ."J-',.'U

slot WlelOll nrs 01 0mg lb inwai cry to compress the sprlng 34:. In order to insert the end member into the slot 30 or to remove it therefrom after it has been placed in opera- :tive position, .it must be pushed in toward the'base' of the slot and at the same time moved throughthe slot in therequired di- TQCtlOIl.

.Thei'keeper 29 upon the" door frame receives the end member of'the'chain in a re The overhanging walls are cess or slot 2966 having overhanging walls 296 beneath which the part 27 r the part 28 is received as shown in Figure 2. The spring 34 of the end member holds the enlarged. end thereof outwardly against the overhanging edge 29?) and the end of the chain is thus firmly held in the keeper so that it is not apt to become dislodged accidentally. Referring now to Figure 2 wherein the bolts 17 air-c1 18 are in retracted position, there is positioned in the base of the slot 30 an outwardly projecting member In Figure 1', wherein the bolts 1! 18 are in extended or operative position, the member 36 is moved downwardly out of the slot 30. This member 36 is shown in operative position. in the base of the slot 30, in Figure 6. When thus positionec the member 36 prevents removal of the end member of the chain from the slot. It ispositioned in the path of movement of the projecting member 33 and therefore the end member of the chain cannot be moved through the slot toward the end thereof for removal. Also, the member 36 when operative is positioned beneath the part 28 of the end member of the chain so that the end member cannot be pushed inwardly to compress the spring 34, and release the part .Z'Y-from itsretaining wall 35. Thus, when the member 36 is in operative position, as shown in Figure the end member of the chain is dependably looked a 'ainst removal from the slot 30 andchence from its connection with the door.

The member 36 is preferably formed in the shape shown in Figure 6, having an enlarged head, which is adapted to be positioned in theslot 30, and a shank portion 37. This shank portion 37 extends through a slot 38 in the base of the groove 30 and is secured toan arm 39. The arm 39 extends angularly of the casing and, as shown in Figures 3. and

4, it is ivotally connected at its end 39a to the slidingplate member 20. This conl, the member 36 slides along "he slot 33 toits operative position within the recess or slot 30.

It will oe seer. that h s o. highly advantageous. n the auxiliary chain is operative it cannot be rendered inoperative unless thebolts 17' and 18 are extended, that is, unless the main lock mechanism for holding the door in fully closed positlon' is operated. Then the bolts'are extended the locking part 36 is automatically ISO (SCI

rendered inoperative and when the bolts are retracted the partx36 is automatically rendered operative. Assumingthat the door is closed and that both bolt-lock and chain mechanism are in operative position and it is desired to respond to a caller, the bolts 17 and 18 are retracted by means of the handle 22 and the auxiliary chain permits the door to be opened a short distance. lVhenthe bolts are thus retracted the end of the chainis automaticall locked against removal from the door and, before the door can be fully opened, the handle 22 must be again turned to extend the bolts and move the member 86 out oi? the path or the chain member. 7

From the foregoing, it will be seen that there is herein provided a construction which achieves the objects of this invention and ac complishes advantages of practical value As many possible embodiments may be made of the above invention and as many changes might be made in the embodiment above set forth, it is to be understood that all natter hereinbe'fore set forth or shown in the accompanying drawings, is to be interpreted as illustrative andqnot'in a limiting sense.
